My research in August:

I used nano-AlN powder to produce third series of composites with 7475 aluminium alloy matrix. As previously, the composites were produced through powder-metallurgy processing. Pre-alloyed 7475 aluminium powders were mixed with ceramic particles and milled in a high energy planetary ball mill.

I also made an literature review concerning heat treatment of composites with aluminium alloy matrix with particular emphasis on precipitation hardening in aging process.
